SI52112-B6-GM3

Overview

The SI52112-B6-GM3 is a two-output PCIe clock generator manufactured by Skyworks Solutions, Inc. It operates within a supply voltage range of 3.13 V to 3.46 V and draws a typical operating current of 17 mA. The device supports a maximum output frequency of 100 MHz with a maximum input frequency of 25 MHz. It features a jitter specification of 250 ps and maintains a duty cycle of up to 55%. Packaged in an 8-lead TDFN format, it functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Two-output configuration designed for PCIe clock generation
• Maximum output frequency of 100 MHz with 250 ps jitter
• Operates on 3.3 V nominal supply (3.13 V to 3.46 V range)
• Compact 8-lead TDFN surface-mount package

Applications

• PCI Express clock distribution systems
• High-speed digital interface timing
• Server and storage backplane designs

Procurement Notes

Verify the specific suffix GM3 against official Skyworks documentation to confirm pinout compatibility and RoHS status. Confirm lead availability directly with authorized distributors as inventory levels fluctuate. Ensure the ordering part number matches the required package type and temperature grade before finalizing procurement orders.

Selection Notes

Select this component when a dual-output HCSL clock solution is required for PCIe applications. Compare the 250 ps jitter performance against system requirements. Verify that the TDFN-8 footprint fits the PCB layout constraints. Ensure the 3.3 V supply rail stability meets the 3.13 V to 3.46 V operational window specified in the datasheet.

Part Context

This part belongs to the SI52112 family of silicon clock generators. It serves as a successor or alternative to earlier variants like the SI52112-A2 series, offering updated packaging and potentially improved specifications while maintaining compatibility with standard PCIe timing requirements.

Replacement Considerations

The SI52112-B6-GT is identified as a manufacturer-recommended replacement for the discontinued SI52112-A2-GT. Verify if the B6 series offers direct pin-to-pin compatibility with existing A2 designs without requiring schematic changes.
